grasshopper jumps maximum distance when Ф = 45 deg
Horizontal component of velocity = u /√2
R = U² / g u = √gR = √10*1.6 = 4 m/sec
Distance in 10 sec: 4/√2 * 10 = 20√2 m
Horizontal component of velocity = u /√2
R = U² / g u = √gR = √10*1.6 = 4 m/sec
Distance in 10 sec: 4/√2 * 10 = 20√2 m

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
